Problems solved by technology

At present, there are a number of products and patents related to Dendrobium candidum in my country. The State Food and Drug Administration has included more than 50 kinds of health products using Dendrobium as raw materials, of which 42 kinds use Dendrobium as the main raw material, such as Tiepi Fengdou Granules, Dendrobium buccal tablets, Dendrobium candidum oral liquid, etc., but most of these products stay on the overall function of Dendrobium candidum, and the depth and breadth of the development and utilization of natural active substances are far from enough
[0004] As the fresh products of Dendrobium candidum should not be stored for a long time, although the storage time can be extended after drying, the sensory indicators will deteriorate, and it is not very convenient to eat, especially the main active ingredient polysaccharide, which is mostly insoluble or only slightly soluble in water In addition, the viscosity of the polysaccharide component is relatively high, and it cannot be micronized by ordinary crushing methods, so that the polysaccharide component cannot be fully absorbed by the human body, and the waste is relatively large, resulting in a decrease in its efficacy
In addition, the existing Dendrobium officinale products are mostly in the form of flakes or pills. Due to the large particles, they disperse slowly after entering the stomach, which is not conducive to the absorption of polysaccharides by the human body. At the same time, it is inconvenient to eat. Most users take it as medicine , not conducive to large-scale promotion

Abstract

The invention discloses a method for increasing the leaching rate of polysaccharide components in dendrobium candidum. The method includes the steps of preprocessing, extraction and post-processing. The method specifically includes the steps that fresh dendrobium candidum strips are cleaned, air-dried and dried for 3.5-4.0 h at the temperature of 95-105 DEG C till the water content is 15-30%, the fresh dendrobium candidum strips are cut into short strips a with the length being 4.0-5.0 cm, a dendrobium candidum pre-extraction material b is obtained after swelling cell disruption is conducted on the short strips a and the short strips a are smashed and screened through a sieve with 100-300 meshes, water with the weight 4-8 times that of the pre-extraction material b of dendrobium candidum is added into the pre-extraction material b, the pre-extraction material is extracted three to four times at the temperature of 80-100 DEG C, each time extraction lasts for 1-3 hours, and extraction solutions are combined, filtered and concentrated to obtain an extract c with the relative density being 1.1-1.3; the extracted extract c is dried, smashed and screened to obtain a target extract. Production equipment investment is little, technological operation is easy, conditions are easy to meet, energy consumption in the preparation process is low, cost is low, processing is convenient, and reagents in use are free of toxin and harm, safe and environmentally friendly. The polysaccharide components in a prepared dendrobium candidum product are easy to leach, and the leaching rate of the polysaccharide components in the dendrobium candidum is increased.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine preparation, and in particular relates to a method for increasing the leaching rate of polysaccharide components in dendrobium officinale. Background technique [0002] Dendrobium officinale is a plant of the genus Dendrobium in the family Orchidaceae ( Dendrobium officinale Kimura et Migo), named for its iron-green skin. Dendrobium plants can be divided into dozens of varieties such as Tiepi, Nobile, Huoshan, Huangcao, Huancao, and Horsewhip according to their shape and origin. Among them, Dendrobium candidum is the most precious. The fresh stems of Dendrobium candidum can be eaten directly, stewed in soup, made into tea, or soaked in wine, and are usually processed into dry products, such as Tiepi Fengdou and Dendrobium candidum functional drinks. In recent years, more and more high-grade health products are produced from Dendrobium candidum, which are sold well in Europe...
